CHARLES E. ZIMMERMANN, OF` SYRAOUSE, -NEW YORK.

MARKING-GAGE.

SPECIFICATION forming part of Letters Patent No. 349,330, datedSeptember 21, 1886.

Application filed May 20, 1886.

To all whom, it may concern,.-

, Be it known that I, CHARLEs E. ZIMMER- MANN, of Syracuse, in thecounty of Onondaga, in the State of New York, have invented new anduseful Improvements in Carpenters Gages, of which the following, takenin connection with the accompanying drawings, is a full, clear, andexact description.

This invention consists in a novel construction of a gage designed forAuse in carpentry, and to accurately, quickly, and conveniently mark orprint out the locations and outlines of mortises to be cut. In theaccompanying drawings, Figure l is a plan view of Iny invention asemployed for marking on 'a Window-frame the mortise for Fig. 2 is a faceview of the gage. Fig. 8 is a side view of the same; and Fig. 4 is atransverse section on line x x, Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents a straight bar adapted togbe inserted in the groove B,which is usually formed in the vertical sides of the window-frame forthe reception of the dividing strip between the two sashes ofthe window.One end off the bar A has secured to it a plate, a, which projects atright angles from opposite sides of said bar, and formslaterally-projecting abutments thereon, for the purpose hereinafterexplained. To the opposite end of the bar A are adj ustably connectedtwo arms, C C', which project from opposite sides thereof, andareprovided with slots b b at right angles'to the bar A, through whichslots pass the screws c c, which fasten the said arms on the upper sideof the bar. The free ends of the arms O C have integral withthem orrigidly attached to them bars O O,"which.are thus carried 1ongtndinallyby the sides of the bar A, and the 'under side of said bars are providedwith pricking or marking points e e, which stand in rows parallel withthe bar A, and are properl y spaced, so that when pressed into thesurface of the window-frame each impression of said points shallindicate the center into which to insert the point of the auger by whichthe mortise is to be bored out, as represented by dotted lines in Fig. 1of thedrawings.

In using my invention the bars C C are to be set ont from the sides ofthe bar A, to bring the rows of points e e to coincide with the lon-Serial No. 202,721. (No model.)

of the groove B by the mortise D, cut in the side piece of thewindow-frame for the attachment of the top cross-piece of said frame.The bars O C are thus carried at the requisite distances` from themortise D to correspond to the distance required between the top rail orcross-piece of the window-frame and the sashpulley. After the' gage isplaced in its aforesaid position a blow or pressure applied to the backof the bar A causes the markers or points e e of the bars C C to maketheir impressions in the surface of the side rail of the windowframe. Aseries of such side rails may thus be marked uniformly, accurate, andexpedi- .the bar A. Neither-d'0 I limit myself to the employment of twomarking-bars at opposite sides of the bar A, because in some cases onlyone of said marking-bars may be required.

What I claim as my invention is The within-described carpenter-s gage,consisting of the bar A, provided at one end with thelaterally-projecting abutment a, the laterally-projecting arms C C',adjustably connected to the opposite end of the bar A, and the markingbar or bars O C, arranged longitudinally by the side of the bar A andrigidly attached to the arms O C', substantiall y as specified andshown.

In testimony whereof I have hereunto signed my name and aiiixed my seal,in the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 18th day of May, 1886.
